1 Samuel 21:8

And David said unto Ahimelech After he had given him some of the loaves of the shewbread:

and is there not here under thine hand spear or sword? any weapon, meaning in the tabernacle, and in his keeping, and at his disposal; he knew the sword of Goliath was there, and perhaps had a principal view to it, and put this question in order to get that in his possession:

for I have neither brought my sword nor my weapons with me; neither his sword, nor any part of his armour, but was come quite naked and unarmed and, as he pretended,

because the king's business required haste; still continuing his lie; whereas the true reason was, he was let down in haste by his wife through a window of his house, and could not stay to take his armour with him; and had lain hid for some time, and passed incognito from place to place, and without armour, that he might be the less known and observed, and least suspected; though it may seem strange that Jonathan had not provided him with a sword.
